I think what you are facing are spurious and confounding
variables.Because one thing is happenin there is a tendencey to relate it
to all the problems .Example you go out in the cold and you catch a
cold.The cold must cause a cold when infact the cold has nothing to do
with a cold it's a virus. I know this doesn't help solve your problem but
over the past many years I've learned this lesson the hard way. Look for
seperate problems first before confounding the problem by trying to
connect all the malfunctions together. I'm not sure about the Midget
engine but if you can get the oil pan off it's fairly easy to check the
big end bearings. Pull the oil pan, bend back the locking tabs on the
bolts on the connecting rods,undue the bolts, push the piston up into the
cylinder and remove the top bearing and the bottom bearing. They don't
look like bearings they are actually a shell that fit into the connecting
rod. If you see any copper color they are shot and need to be replaced.
The correct size for the new ones should be determined by measuring the
surface on the crank shaft that the bearings ride on . You should be safe
to replace with the same size that came off. They should have the size
printed on them. Be sure to replace each bearing cap on the same
connecting rod that it came from. Torque the bolts and replace the lock
tabs. One thought to add to your list you may have a bad clutch, this can
cause vibration. What happens when you push the clutch in as the car is
vibrating
